Thrust Fehler Upgrade von CUDA 4.0 auf 8.0

Question

Ich versuche, dieses Projekt (https://github.com/ashwin/gStar4D), die in CUDA 4.0 bis 8.0 geschrieben ist, zu aktualisieren. Aber ich bin immer eine Tonne Kompilierungsfehler von Thrust auf Zeilen wie diese:

thrust::sort_by_key( orderVec.begin(), orderVec.end(), 
          thrust::make_zip_iterator(make_tuple(_pointVec->begin(), _scaledVec->begin()))); 

Die Fehler sind in der Regel ‚Fehler: Klasse‚Schub :: tuple_size <>‘hat kein Mitglied‚Wert‘‘, ‚Fehler: unvollständiger Typ ist nicht erlaubt‘oder‚Fehler: Name, gefolgt von ‚::‘ muss eine Klasse oder Namespace-Name sein‘

Irgendwelche Gedanken darüber, was das Problem sein könnte?

Answer 1

Wie Robert oben vorgeschlagen, nur Schub hinzuzufügen benötigt :: to make_tuple:

thrust::sort_by_key( orderVec.begin(), orderVec.end(), 
         thrust::make_zip_iterator(thrust::make_tuple(_pointVec->begin(), _scaledVec->begin()))); 

Nur eine PR mit allen notwendigen Änderungen vorgelegt 8.0 hier auf Cuda auszuführen: https://github.com/ashwin/gStar4D/pull/1
